Review how your own protection is built: which modules are protected, what they call, and where the design rests on an assumption that may not hold.
DRM architecture analysis documents the protected modules, interfaces, load behavior and trust boundaries of a digital rights management system. For rights holders and authorized reviewers, Devirt records how components communicate, where entitlement checks happen and which assumptions the design relies on. The deliverable is an architecture report with supporting evidence and explicit analysis limits.
Family recognition is an intake decision, not a guarantee for every build. Custom behavior and multiple protection layers can require a separate assessment.
A binary does not need virtualization to be in scope. Devirt can reverse ordinary compiled programs, map their behavior and interfaces, and surface risk indicators for your authorized review.
The delivery pairs readable output with a full ledger for the agreed scope. Proven, runtime-dependent, unresolved, and permanently bounded units remain distinguishable, including units that were never virtualized.
See how the checks workThis service documents how a protection is put together, for the people who own it or are authorized to examine it. A review answers questions such as where the entitlement check actually happens, what the protected modules import, which components have to trust each other, and what an attacker would see first.
Devirt does not remove DRM and does not circumvent access controls. It does not unlock protected content, defeat license checks, or produce anything whose purpose is to get around a protection. Requests with that aim are declined, and a supported protector family does not by itself establish permission to analyze a particular binary.
Rights holders and protection vendors who want their own protection design reviewed before or after release.
Interoperability and compatibility teams with authorization to make their own product work correctly alongside protected software.
Compliance, audit and IP teams who need a written, evidence-backed account of how a protected component behaves.
Devirt documents the protected modules and how they are packaged, the imports and platform calls they rely on, the boundaries between protected and unprotected code, and the order in which the pieces load and hand off to each other.
Where a module is virtualized by a commercial protector, recovery of its logic is what makes the rest of the picture legible, because a decompiler otherwise describes the protector rather than the module. The recovered logic is reported with the same evidence rules as any other Devirt result.
A review arrives in the output you choose: an IDA database, annotated pseudocode, a full reverse engineering report, LLVM IR or structured API JSON. For most architecture work the written report carries the findings and the other formats carry the evidence behind them.
Every result carries its coverage ledger for the agreed scope, so a finding can be checked rather than taken on trust.
Readable output is not the same as proven output. Devirt records every unit in scope in one of four coverage categories, and the four counts add up to the total, so nothing drops quietly out of the record.
A conclusion about an architecture is only as strong as the units under it. Where a component stays runtime-dependent or unresolved, the report says so instead of rounding the finding up.
Architecture work is scoped before it begins. Devirt reviews what you send, agrees the scope and the questions in writing, and quotes the work. Nothing is charged unless you accept the written offer, and a revised scope needs your approval.
Confidentiality, any EU requirements and exclusivity are agreed before a transfer, and US government or export-controlled work requires a separate written contract before anything is submitted.
You must own the submitted binary or hold authorization to analyze it, and use the results lawfully. Devirt may ask you to clarify the scope or the authorization, and reserves the right to decline an engagement.
Analysis runs in isolation, files are not shared between customers, and uploads are never used for training. Your file is used only for the work you requested. You can request your own processing log, and Enterprise deletion certificates require confirmed deletion rather than a request to delete.

Readable code explains the behavior. The ledger explains how far you can rely on it.

Start a free assessmentNo. Devirt analyzes how a protection is built for the people entitled to know; it does not remove DRM, circumvent access controls, defeat license checks or unlock content, and it declines any request with that aim. If that is what you are looking for, this is not the service.
No. Devirt does not build, license or resell a DRM product. It reviews protection designs that already exist, which is why a review can look at your own system without any interest in selling you a replacement for it.
Yes, where you hold the rights to the software or written authorization from the party that does. This includes protection commissioned from a third party, where you hold the necessary rights or authorization. Devirt may ask how that authorization is established before starting.
It stays visible. Units that cannot be proven remain in the ledger as runtime-dependent, unresolved or permanently bounded rather than being dropped, and the report states which findings rest on them. The scope and likely coverage are estimated before any paid work begins.
Yes. Analysis runs in isolation, files are not shared between customers, uploads are not used for training, and your file is used only for the work you requested. Confidentiality terms are agreed before transfer, and released output is retained for 72 hours by default or 30 days on Team.

Input deletion follows delivery. This timeline shows the default 72-hour output window. Team outputs are kept for 30 days. Audit records have a separate 90-day window.
Policy illustration, not a live deletion certificate. Deletion is confirmed from provider receipts. Assessment inputs, unpaid jobs, and account/billing records have their own rules in the policy.
